activemq队列模式基本操作

package site.zy9.jms.queue;

import javax.jms.Connection;
import javax.jms.ConnectionFactory;
import javax.jms.Destination;
import javax.jms.JMSException;
import javax.jms.MessageProducer;
import javax.jms.Session;
import javax.jms.TextMessage;

public class AppProducer {

	final static String URL = "tcp://192.168.137.3:61616";
	final static String QUEUENAME = "myQueue";
	
	public static void main(String[] args) throws JMSException {
		//1.创建连接工厂
		ConnectionFactory connectionFactory = new org.apache.activemq.ActiveMQConnectionFactory(URL);
		
		//2.创建连接
		Connection connection = connectionFactory.createConnection();
		
		//3.启动连接
		connection.start();
		
		//4.创建会话 第一个参数表示是否使用事务，第二个表示应答模式
		Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);
		
		//5.创建目的地
		Destination destination = session.createQueue(QUEUENAME);
	
		//6.创建生产者
		MessageProducer messageProducer = session.createProducer(destination);
	
		//7.创建消息
		for(int i=0;i<100;i++){
			TextMessage textMessage = session.createTextMessage("message:"+i);
			//8.发送消息
			messageProducer.send(textMessage);
			System.out.println("message "+i+"发送成功");
		}
		
		//9.关闭连接，防止连接被耗尽
		connection.close();

					e.printStackTrace();

		//8.关闭连接 close操作应该等到应用程序结束前再关闭
//		connection.close();
